Multi-tabling has drastically changed the way the game of poker is played, allowing players to grind an unprecedented volume of hands and make a living at the lower stakes, while offsetting, to a degree, the swings and variance of the game. Mobile technology, meanwhile, has been the biggest driver of growth in the gambling industry over the last few years, and the speed of adoption of this technology has been unparalleled. For example, it took radio 38 years to reach 50 million users, but just 36 days for Angry Birds to reach the same level of penetration.
